AT&T has expanded its VoLTE and HD Voice offering in a number new markets.
According to a press release, AT&T has rolled out VoLTE and HD Voice in select areas in the District of Columbia, Georgia, Illinois, Indiana, Maryland, Michigan, Minnesota, Nevada, North Carolina, Ohio, Oregon, Pennsylvania, South Carolina, Texas, Utah, Virginia, Washington and Wisconsin, with more to come.
In a blog on the topic, AT&T SVP of Technolgy and Operations John Donovan said that AT&T’s internal testing shows the VoLTE network performance is strong. During the month of November, AT&T said that those tests showed an average of better than 99 percent in both accessibility and retainability overall.
“We are committed to delivering an outstanding customer experience with our VoLTE rollout, and will continue to optimize, test and expand our VoLTE coverage throughout 2015,” Donovan said. “We also expect to see more VoLTE-capable devices available by year’s end and next year, as well.”
T-Mobile and Verizon have also launched VoLTE, while Sprint has pushed its HD voice offering. AT&T and Verizon recently announced plans to work on VoLTE interoperability between their two networks. Dononvan said that AT&T is currently working with other wireless carriers on this same functionality, too.
